Consolidated PBY-5A Catalina, 1942. (U.S. Naval History and Heritage Command 80-G-K-14896)
3 June 1942: At dawn, twenty-two U.S. Navy PBY-5A Catalina patrol bombers launched from Midway Island to search for a Japanese fleet which was expected to be heading toward the American island base. One of them, 44-P-4, (Bu. No. 08031) commanded by Ensign Jewell Harmon (“Jack”) Reid of Patrol Squadron 44 (VP-44), sighted Admiral Raizo Tanaka’s Midway Occupation Force, 700 nautical miles (1,296 kilometers) west of the atoll, shortly before 9:00 a.m.

The Catalina scouted the enemy task force, which they believed to be the “main body” of the Japanese fleet and radioed information back to their base. The task force consisted of 1 light cruiser, 12 transports carrying 5,000 soldiers, 11 destroyers, 2 seaplane tenders, 1 fleet oiler and 4 patrol boats.

The PBY-5A was an amphibious variant equipped with retractable tricycle landing gear. It was 63 feet, 10-7/16 inches long (19.468 meters) with a wing span of 104 feet, 0 inches (31.699 meters) and overall height of 20 feet, 2 inches (6.147 meters). The parasol wing was mounted above the fuselage on a streamlined pylon and supported by four external braces. The wing has 6° incidence and the center section has no dihedral or sweep. The outer wing panels are tapered. There are no flaps. The total wing area is 1,400 square feet (130 square meters). The PBY-5A had an empty weight of 20,910 pounds (9,485 kilograms), and gross weight in patrol configuration of 33,975 pounds (15,411 kilograms). Its maximum takeoff weight (land) was 35,420 pounds (16,066 kilograms).

The PBY-5A was powered by two air-cooled, supercharged, 1,829.4-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1C3-G (R-1830-92) two-row 14-cylinder radial engines. These were rated at 1,200 horsepower at 2,700 r.p.m. at Sea Level for takeoff. The maximum continuous rating for normal operation was 1,060 horsepower at 2,550 r.pm., up to 7,500 feet (2,286 meters). The engines drove three-bladed Hamilton Standard controllable-pitch propellers with a 12 foot, 1 inch (3.683 meter) diameter through a 16:9 gear reduction. The R-1830-92 is 48.19 inches (1.224 meters) long, 61.67 inches (1.566 meters) in diameter, and weighs 1,465 pounds (665 kilograms).
The PBY-5A Catalina had a cruise speed of 124 miles per hour (200 kilometers per hour). Its maximum speed was 169 miles per hour (272 kilometers per hour) at Sea Level and 179 miles per hour (288 kilometers per hour) at 7,000 feet (2,134 meters). The service ceiling was 14,700 feet (4,481 meters) and maximum range was 2,545 miles (4.096 kilometers) at 117 miles per hour (188 kilometers per hour.).
The patrol bomber could carry 4,000 pounds (1,814 kilograms) of bombs or depth charges, or two torpedoes on hardpoints under its wing. Two Browning M2 .30-caliber air-cooled machine guns were mounted in a nose turret with 2,100 rounds of ammunition. A third .30-caliber machine gun was positioned in a ventral hatch with 500 rounds of ammunition. Two Browning AN-M2 .50-caliber heavy machine guns were mounted in the waist with 578 rounds of ammunition per gun.
3,305 Consolidated PBY Catalina’s were built, of which 802 were the PBY-5A variant. In addition to United States service, many other countries operated the Catalina during and after World War II. The last PBY in U.S. service was a PBY-6A which was retired 3 January 1957.

12 May 1938: Three Boeing B-17 Flying Fortress four-engine heavy bombers of the 49th Bombardment Squadron, 2nd Bombardment Group, departed Mitchel Field, Long Island, New York, in heavy rain and headed eastward over the Atlantic Ocean. Their mission, assigned by Major General Frank M. Andrews, commanding General Headquarters, U.S. Army Air Corps, was to locate and photograph the Italian passenger liner, S.S. Rex, then on a transatlantic voyage to New York City. The purpose was to demonstrate the capabilities and effectiveness of long-range bombers.

The flight was led by Major Caleb Vance Haynes, commanding officer of the 49th Bombardment Squadron, flying B-17 number 80. The 2nd Bomb Group commanding officer, Lieutenant Colonel Robert Olds, was aboard Haynes’ B-17, along with an NBC radio crew to broadcast news of the interception live across the country. Reporters from the New York Times and the New York Herald Tribune were aboard the other airplanes.
1st Lieutenant Curtis Emerson LeMay, Air Corps, United States Army.
The planning of the interception and in-flight navigation was performed by First Lieutenant Curtis E. LeMay. Position reports from S.S. Rex were obtained and forwarded to LeMay as the aircraft were taxiing for takeoff.
The flight departed Mitchel Field at 8:45 a.m. They encountered heavy rain, hail, high winds and poor visibility, but at 12:23 p.m., the Flying Fortresses broke out of a squall line and the passenger liner was seen directly ahead. They flew alongside the ship at 12:25 p.m., 620 nautical miles (1,148.24 kilometers) east of Sandy Hook, New Jersey. They were exactly on the time calculated by Lieutenant LeMay.
The B-17s made several passes for still and motion picture photography while NBC broadcast the event on radio.
Colonel Olds would rise to the rank of Major General and command 2nd Air Force during World War II. He was the father of legendary fighter pilot Brigadier General Robin Olds. Major Hayes served in various combat commands and retired at the rank of Major General in 1953.
Curtis LeMay would be a major in command of the 305th Bombardment Group, a B-17 unit, at the beginning of World War II. He personally led many combat missions over Europe, and would command the 4th Bombardment Wing, then the 3rd Air Division. By the end of the war, he was in command of XXI Bomber Command based in the Marianas Islands. From 1948 to 1957, General LeMay commanded the Strategic Air Command. He served as Vice Chief of Staff of the Air Force., 1957–1961. General LeMay was Chief of Staff, United States Air Force, from 1961 to 1965.
At the time of the interception of the Rex, there were only 12 B-17s in the Air Corps inventory: the original Y1B-17 service development airplanes. By the end of production in 1945, 12,731 B-17 Flying Fortress bombers had been built by three aircraft manufacturers.

26 April 1939: The United States Army Air Corps placed an order for 524 Curtiss-Wright P-40 Warhawks. This was the largest production order for any U.S.-built fighter since World War I. The total cost was $12,872,398.¹
The order was authorized by the Air Corps Expansion Act, approved by Congress 3 April, and signed by President Roosevelt on 26 April 1939.
The Curtiss-Wright Corporation Hawk 81 (P-40 Warhawk) was a single-seat, single-engine pursuit, designed by Chief Engineer Donovan Reese Berlin. It was developed from Berlin’s radial-engine P-36 Hawk. The P-40 was a low-wing monoplane of all-metal construction and used flush riveting to reduce aerodynamic drag. It had an enclosed cockpit and retractable landing gear (including the tail wheel). Extensive wind tunnel testing at the NACA Langley laboratories refined the airplane’s design, significantly increasing the top speed.

The new fighter was 31 feet, 8-9/16 inches (9.666 meters) long with a wingspan of 37 feet, 3½ inches (11.366 meters) and overall height of 9 feet, 7 inches (2.921 meters). The P-40’s empty weight was 5,376 pounds (2,438.5 kilograms) and gross weight was 6,787 pounds (3,078.5 kilograms).
The P-40 was powered by a liquid-cooled, supercharged, 1,710.597-cubic-inch-displacement (28.032 liter) Allison Engineering Co. V-1710-C15 (V-1710-33). This was a single overhead cam (SOHC) 60° V-12 engine designed by Harold Caminez, Allison’s chief engineer. The V-1710-33 had a compression ratio of 6.65:1. It was rated at 930 horsepower at 2,600 r.p.m. at 12,800 feet (3,901 meters), and 1,040 horsepower at 2,800 r.p.m. for takeoff, burning 100-octane gasoline. The engine turned a three-bladed Curtiss Electric constant-speed propeller through a 2:1 gear reduction. The V-1710-33 was 8 feet, 2.54 inches (2.503 meters) long, 3 feet, 5.88 inches (1.064 meters) high, and 2 feet, 5.29 inches (0.744 meters) wide. It weighed 1,340 pounds (607.8 kilograms).

The fighter (at the time, the Air Corps designated this type as a “pursuit”) was armed with two air-cooled Browning AN-M2 .50-caliber machine guns on the engine cowl, synchronized to fire through the propeller, with 380 rounds of ammunition per gun. Provisions were included for one Browning M2 .30-caliber aircraft machine gun, with 500 rounds of ammunition, in each wing.
The first production P-40 Warhawk, 39-156, made its first flight 4 April 1940. The 8th Pursuit Group at Langley Field, Virginia, was the first Army Air Corps unit to be equipped with the P-40.

After 200 P-40s were produced for the Air Corps, production was interrupted to allow Curtiss-Wright to build 100 Hawk 85A-1 export variants for the French Armée de l’air, then engaged with the invading forces of Nazi Germany. When France surrendered 22 June 1940, none of these airplanes had been delivered. The order was then assumed by the British Royal Air Force as the Tomahawk I.
U.S. Warhawk production resumed as the improved P-40B, and the remainder of the P-40 order was cancelled.

On 26 April 1939, the U.S. Army Air Corps ordered 524 P-40 Warhawks, the largest single aircraft order up to that time. Only 200 of these aircraft were produced in the P-40 configuration. The Army deferred its order to allow Curtiss-Wright to produce Hawk 81A fighters for France, however that nation fell to enemy forces before any could be delivered. 140 of these French contract fighters were taken over by Britain’s Royal Air Force, which designated them as the Tomahawk Mk.I. Another 16 P-40s were delivered to the Soviet Air Force, having been purchased with gold.

Henry Lloyd Child was born at Philadelphia, Pennsylvania, 25 May 1904, the second of two children of Edward Taggart Child, a consulting engineer in shipbuilding, and Lillian Rushmore Cornell Child. He was baptised at the Church of the Good Shepherd, Rosemont, Pennsylvania, 22 December 1913. Child graduated from Flushing High School in Flushing, New York, then attended the Haverford School in Philadelphia.
Henry Lloyd Child, 1926. (The Class Record)
“Skipper” Child majored in mechanical engineering at the University of Pennsylvania where he was a member of the Hexagon Senior Engineering Society and the Phi Sigma Kappa (ΦΣΚ) and Sigma Tau (ΣΤ) fraternities. He was a member of the varsity and all-state soccer team (left halfback), and also played football and tennis. Child graduated with a bachelor of science degree, 15 June 1926.
After graduation from college, Child went to work for the Curtiss-Wright Corporation as a engineer.
Child joined the United States Navy, 23 November 1927. He was trained as a pilot at Naval Air Station Hampton Roads, Norfolk, Virginia, and was commissioned as an Ensign. He was promoted to lieutenant (junior grade), 7 November 1932, and to lieutenant, 11 November 1935.
While maintaining his commission in the Navy, Child returned to Curtiss-Wright as a test pilot. He made the first flight of the P-36 Hawk.
Mr. And Mrs. Henry Lloyd Child (née Allene Anne Gausby), 28 October 1939.
Henry Lloyd Child married Miss Allene Ann Gausby of Hamilton, Ontario, Canada, 28 October 1939. They had met in July 1938, while playing in a tennis tournament at Muskoka, Northern Ontario. They would have a daughter, Beverley L. Child.

Child became famous as the “World’s Fastest Human” when he put a Hawk 75A demonstrator into a vertical dive from 22,000 feet (6,706 meters) over Buffalo Airport, 24 January 1939. It was believed at the time that he had reached a speed in excess of 575 miles per hour (925 kilometers per hour). A contemporary news report said that the needle of the recording instrument had gone off the edge of the graph paper, and that the actual speed may have been faster than 600 miles per hour (966 kilometers per hour).
H. Lloyd Child’s high speed dive was the subject of an 8-page article in True Comics #6, November 1941. (Parents’ Magazine Press)
H. Lloyd Child worked for Lockheed from 1958 to 1968, when he retired. He died at Palmdale, California, 5 August 1970 at the age of 66 years.

Kawasaki Ki-48 Army Type 99 twin-engine light bomber. Allied reporting name, “Lily.”
20 December 1941: For the first time, the 1st American Volunteer Group (the “Flying Tigers”) engaged aircraft of the Empire of Japan in combat. 1st and 2nd Squadrons, based at Kunming, China, intercepted ten Kawasaki Ki-48-I Army Type 99 twin-engine light bombers of the 82nd Dokuritsu Hiko Chutai.
Japan and China had been at war since 1937. The Japanese aircraft were based at the Gia Lâm airport, near Hà Nội in occupied French Indochina. They had frequently attacked Kunming, a Chinese city at the northern end of the Burma Road, and had previously been unopposed. For this mission, the bomber squadron initially had a fighter escort, but the fighters turned back at the Indo-China/China border.
The AVG had established a network of observers which would report enemy aircraft in time for the fighters to take off to intercept them. Having received the warning of inbound aircraft, the 1st and 2nd AVG squadrons were ordered into battle.

Sources vary widely as to the number of AVG aircraft involved, but there may have been as many as 16 Curtiss-Wright Hawk 81-A3s from the 1st Squadron, and 8 more from the 2nd Squadron. There is a general consensus that the fighters shot down three of the Japanese bombers, and that a fourth went down while returning to base. Other sources say that only one of the ten Ki-48s made it back to its base. AVG pilots claimed five bombers shot down and two damaged. One Hawk 81 ran out fuel and was damaged beyond repair in a forced landing.
An RAF order for 100 Tomahawk IIb (Curtiss-Wright Hawk 81-A2 ) was released to be available for AVG. They were built as hybrids of the Tomahawk Mk.IIb and the P-40C Warhawk, though the airplanes intended for the AVG differed in details from either the standard Britsih or American fighters. The airplanes were painted in the standard RAF brown and green camouflage patterns. The completed airplanes were knocked down, crated, then shipped from New York. They were reassembled at a CAMCO facility near Rangoon, Burma.
The Curtiss-Wright Corporation Hawk 81 was a single-seat, single-engine pursuit (fighter). It was a low-wing monoplane of all-metal construction and used flush riveting to reduce aerodynamic drag. It had an enclosed cockpit and retractable landing gear. Extensive wind tunnel testing at the NACA Langley laboratories refined the airplane’s design, significantly increasing the top speed.
The Hawk 81 was 31 feet, 8¾ inches (9.671 meters) long, with a wingspan of 37 feet, 4 inches (11.379 meters) and overall height of 10 feet, 7 inches (3.226 meters).

The Tomahawk/Warhawk was powered by a liquid-cooled, supercharged, 1,710.597ubic-inch-displacement (28.032 liter) Allison Engineering Co. V-1710-C15 (V-1710-33), a single overhead cam (SOHC) 60° V-12 engine, which had a Continuous Power Rating of 930 horsepower at 2,600 r.p.m., from Sea Level to 12,800 feet (3,901 meters), and 1,150 horsepower at 3,000 r.p.m. to 14,300 feet (4,359 meters) for Take Off and Military Power. The engine drove a three-bladed Curtiss Electric constant-speed propeller through a 2:1 gear reduction. The V-1710-33 was 8 feet, 2.54 inches (2.503 meters) long, 3 feet, 5.88 inches (1.064 meters) high, and 2 feet, 5.29 inches (0.744 meters) wide. It weighed 1,340 pounds (607.8 kilograms).
Armament consisted of two air-cooled Browning AN-M2 .50-caliber machine guns mounted in the cowling and synchronized to fire forward through the propeller arc, with 380 rounds of ammunition per gun. In British service, the Tomahawk was armed with an additional four Browning .303 Mark II machine guns, with two in each wing. The American P-40, P-40B and P-40C Warhawks had two or four Browning AN-M2 .30-caliber aircraft machine guns as wing-mounted guns.
The “blood chit” was sometimes sewn on AVG pilots’ jackets.
The AVG pilots were employees of the Central Aircraft Manufacturing Company (CAMCO). Most were former United States military pilots who had been secretly recruited. They were required to resign their officers’ commissions. Importantly, they were all civilians—not members of the Chinese military–nor were they otherwise employed by the government of China. They each had a one year contract, 4 July 1941–4 July 1942. They were paid a monthly salary, more than three times their former military pay, and were also paid a bonus for each enemy airplane they shot down.
